ment in Closures, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The object of our invention is to provide for so fastening a cap over the mouthv and about the neck of a milk-bottle, jelly glass or jar, perfume bottle, and the like, for sealing it, as to avoid the use of any form of stopper to enter the mouth and' to facilitate the sealing operation while rendering the removal of the cap easy and convenient. f

In practising our invention we cover the mouth of a bottle or jar with a cap having' a skirted portion extending about the p0rtion of the bottle below its mouth and a tubular fastening'band tightly surrounding the skirt of the cap. The ends of this tubular fastening band are preferably in telescoping engagement. whereby the ends are tightly engaged with each other to hold the band in tight engagement with the closure skirt, though the invention is not to be limited to this telescoping formation of the band. By making the fastening band of tubular formation a variety of advantages aresecured as compared with the results which would follow the use of a solid band. By the use of a hollow band the band is enabled to be /rmly applied to all portions of the closure notwithstanding the irregularities in the formation of the bottles or jars since the bands may be subject to compression where the bottles or jars bulge more. Then again, the tubular bands will adapt themselves to the irregularities in the closure so that the necessary tightt between the closure and the bottle is .se-

cured by thefhollow band that 'thus ada Yts itselflto maintain the tiv ht 'engagement `e tween the closure and ghe bottle.'4 As the invention is preferably ractis'e'dthefastenf ing bands are made o substantially nonresilient material so that afterth'ey have Specification of Letters Patent.

once beenapplied to the closure they cannot be removed from engagement therewith for the purpose of unwarranted access to the bottle without detection vsince the fastening band, if made of non-resilient material, will notspring back in shape afterhaving once been forced. In accordance with one feature of our invention, but to which feature the invention is not to be limited, the skirted portion of the closure haisl an outsetting extension and the tightening ring has a formation in gripping engagement withthis extension and while this feature is preferably practised with y a tightening ring which is hollow, such feature is not to be limited to the employment of a hollow tightening ring.

Like parts are indicated by similar charls 'icters of reference throughout the different gures.

The cap or closure 15 shown may be best formed of comparatively heavy paper, though any other suitable flexible material may be employed, and it is preferably reduced to a permanent cap form ready for application to seat over and cover the mouth of a bottle and encircle the neck, represented at 17 (Figs. Ll and 5), though it may be a flat piece of the material adapted to be folded into cap shape over the bottle mouth and about its neck portion, either way providing the skirt portion 16 of the cap, with the advantage in the prepared cap of enabling Ait to be provided about the free edge of the skirt portion with a seating flange 18 for the fastening band hereinafter described.

'With a formed cap applied to a bottle and encircled by a band of flexible non-resilient metal and of any suitable typeincluding any of the types illustrated, the band isv squeezed or compressed in place to tighten it about the bottle neck and fasten about the same the skirt portion of the cap, thus seali-ng the bottle. This operation may be readily performed by inserting the bottle neck into and operating against it a suitable machine, such as that illustrated in Fig. 1 and denoted, as a whole, by the reference character' 2G. lt involves an annular table 21 on which is rotatably confined a ring 22 provided with an operating'handle 23 and containing, at equal intervals apart, similar oblique slots 24; and from a point adjacent to the inner end of each slot, a rigid bearing 25' projects radially from the inner edge of the annular 'bedtoward its center. ln each nimm? bearing is reciprocally supported a similar neck may be inserted, as by introducing it into the machine from underneath the table 21. `With a bottle neck in the aforesaid annulus and equipped with aband-encircled cap 15, by turning the handle 23 to rotate the ring 22 into the position represented in Fig. 1, the engagement of the cam slots '24 with the studs 27 advances the plungers 26 simultaneously and uniformly to clamp the band between the heads 28 and'fasten it securely in place as hereinafter described; and turning the handle in the opposite direction effects withdrawal of the plungers and release of the bottle.

As will be understood, dealers in the material contained in the bottles will be equipped with machines, such' as the machine 20, for sealing them and also, by preference, with supplies of the caps 15 which are adaptedby their flaring shape to be shippedl to them in nested condition with a lband 19 about each and bearing against the flange 18, ready for applying the cap in place and subjecting the bandV to the action of the machine. A. desirable type of the band is that shown in Fig. 8, which is produced from a sheet metal strip 191 (Fig. 6) by bending it lengthwise upon itself into a tapering tube and reducing this tube into circular form with the narrower `end tele scoping the wider end. Tn subjecting this band to the action of the machine 2U, the encircling plungers compress it about the skirt of the sealing cap to tighten it against the latter, thereby forcing and wedging the narrower end into the Wider end of the annular tube in addition to crimping the band. This same type of band may be produced in the form represented in Fig. 9 from the tapering sheet metal strip 192 of Fig. 7, which diders from that of Fig. 6 in containing an o'set in its narrower end portion. This offset presents, in the band of Fig. 9, a shoulder 193 forming a stop which prevents the action of the machine from driving the narrower into the wider end of the tubular band, so that when the plungers 26 are caused to exert their pressure against this band, which should be set in the machineto bring the telescoping sections into the patlf of one of the plunger heads, the exertion bythe heads of the circumferential compression on the band will crimp it into vthe shape or approximately the shape illustrated in Fig. 10, one of the crimps being formed at the telescoping joint to clench lit as represented at 194. The bandsv of Figs.

11 and v13 are endless, the first named being -a sectional annulus through which a bottle,vv

formed of non-resilient wire' of round crossr section and the other of sheet metal. Obvi` 14. In every instance, however, the non-resilient band is tightened by squeezing it about the cap skirt to fasten the cap into sealing condition upon the, bottle. By making the bands of nonresilient metal the bands hold their shape after being` placed into engagement with the closure skirt.

When the bands are made hollow as described they are nonresilient. If the metal of the band was resilient it would not perform its closure holding function satisfactorily. The nonresilient character .of the band therefore is Aan important feature of our invention. The bottle orl jar, and in the claims we use the term bottle in the broad sense of a bottle or jar, is beaded at its lmouth or outwardly extended adjacent its mouth so that' the inner surface of the lower part of the skirt of the cap may be contracted suificiently to be overhung by the top of the bottle whereby the cap cannot be lifted from the bottle without the enlargement of the non-resilient band. If this band is enlarged its function as a protecting seal is destroyed so that the bottle may'not again be lled without detection. This mode of fastening the cap in place renders it readily removable for emptying the contents of the bottle, since to free it all that is required is to force the band, as with a fork or other suitable implement applied to any point thereon, past the flanged edge of the cap, thereby permitting Athe cover to be readily pulled or torn off or, if desired, the crown portion of the cap may be cut away, thus opening the bottle without disturbing the band. f

Our improvement is peculiarly effective in its purpose in connection with bottles with circumferentially beaded mouths like the representations in Figs. 4 and 5, since, in compressing the band in the manner described, it tends to stretch the cap4 skirt about the bead and thus draw the cap tautly over the bottle mouth, thereby eifectually sealing the bottle because vof the closeness and unyielding character of the seal rendered so by compressing the non-resilient band as described.

In Figs. 15 to 21 inclusive, the closure is shown in the Vform of a iexible fiber,

paper or pastehoard structure having the form of an inverted dish whose skirt portion is attened or folded in a manner to provide recesses 29 between adjacent folds,.

the sides of said recesses converging to points-at the top of the closure and diverging toward tlv` bottom of the closure,

whereby -these sides of the recesses are brought close together when the tightening band is gripped about the skirt portion of the closure. The folds in the skirt portion of the closure are desirably formed as 'illustrated to` constitute a sinuous line of continuously connected U-shaped gatherings, whereby, when the sides of the recesses 29 .are brought close together, three thicknesses or layers of the material of the closure are provided between the tightening band and the neck of the bottle, whereby the material of the closure is suitably thickened or augmented where the tightening band is lo-- cated in order that the tightening band may be embedded in the amplified portion of the closure so as thoroughly to seal the bottle where the tightening band is located ,to prevent the passage of fluid between the interior of the bottle and the exterior thereof, any moisture to which the closure may be subject serving further to amplify the thickness of the closure where the band is located, still further to enable the tightening band to be embedded within the mate- A rial of the closure and improving the liiuid tight connection between the closure and thebottle where the 'band is located. The portion of the closure below the band is obviously thicker than the portion of the closure...immediately underlying the' band, so that the removal of the closure past the band is rendered diiiicult. There arev recesses 30 upon the interior of the closure that also taper to vanishing points at the top of the closure, whereby open spaces between the folds are avoided where the top of the closure engages the bottle mouth, whereby the top of the closure is unprovided with internal passages lor recesses where suchA top of the closure engages the mouth of the bottle, in order further to restrict or obstruct uid passage between the interior and exterior of the bottle. We consider it to be broadly new with us to provide a closure in which the thickness of the skirted portion is amplified and in which such thickened portion coperates with a tightening band of such a character that it may be embedded in the thickened portion of the closure to accomplish the results which have been described, and while we prefer to amplify `vention, we not only cause the clamping ring to force the closure into tight engagement with the bottle neck, but we also klnk'or crimp or convolute the non-resilient tightening ring in such .a manner as4 to pinch an outsetting gathered portion or portions 31 ofthe closure so as to enable the tightening ring positively to grip the ment with a cap, substantially as closure and prevent accidental withdrawal thereof from the bottle, thereby suppleinenting the hold which the tightening ring has upon the skirted portion of the closure due to the embedding of the tightening ring within the thickened portion of the closure. We prefer to provide a plurality of outsetting gathered portions 31 distributed about the bottle and which are thus pinched or gripped by the kinks or folds in the tightening ring, but we do not wish to'be limited to the number of such outsetting gatherings 31 that are employed. The closure, as made in4 accordance with the preferred embodiment of our invention, and the tightening ring that is to be applied thereto, may be subjected to the action of the machine villustrated in Fig. 1 in orde'r that the tightening 4band or ring may have formed therein the gripping loo s that enf gage the outsetting closure gat erings 31, these closure gatherings vbeing formed when the machine is operated to locate the closure and the tightening band in place about the bottle neck, portions of the skirt of the closure that are displaced as the result of the mutual approach of the parts of the head 28 being pressed between these parts and there finding access between the sides of the loops in the tightening ring, which loops are also formed as a consequence of the displacement of the material of the tightening ring between the sections of said head.
